Hi,
> 2) if nodeindex is able of returning a node why not having it (perhaps called "nodeatindex") working for all kind of repeated structures and returning the focused/selected node so people can more easily get stuff done in general with repeats when they know their ID even if they are not in a position of knowing or dealing with their binding expression?

yes, this function would be extremely useful for repeat as well.
Actually, in X-Smiles we support this function for repeats as well.
